Page 11: Configuration Of The Parameters With "Fr 4 Copy-Key
7 Configuration of the parameters with “FR 4 copy-key” FR4 copy-key: Konvekta part no. H11-001-396-C for FR4, FR4.1 and FR4 Pharma The unit has a plug socket. Via this plug socket the operating parameters are transmitted from and to the unit. For this the FR4 copy-key with 5-pole plug is used. The FR4 copy-key is used for fac- tory programming of units that should have the same parameter configuration, or for a backup of the programming of a unit so that this can be reconstructed quickly if required. -
